Captain George Vancouver visited Maui, anchoring at Lahaina. He noted the island appeared impoverished by years of war with little surplus food to offer in trade. Vancouver stopped in Hawai'i three times during 1791-1794, wintering his ships between stints of mapping the northwest coast of America. Vancouver had also visited the Islands with Cook's second and third voyages. As captain of his own ships, he acted as negotiator and peacemaker between warring Hawaiian chiefs and helped patch up relations between Kamehameha and his favorite wife Ka'ahumanu; he refused to sell any firearms to chiefs, but gave them beef, cattle, geese, sheep and goats.
